The early mobiles were normally huge, heavy and useless. The most popular mobile was the can phone made by Motorola, as seen in the picture. There was also a type of mobile, called the portable phone, which was cheaper and had a separate battery pack, aerial and handset/receiver. It was made to look like a bag.
I remember having an x-ray once and a Yuppie decided to get off the x-ray table (shared room) to answer his oh so important call.
I remember the Dr's shouting at him "It looks as though your mobile is more precious to you than your life"!!!!
